56 THE CULTIVATED EVERGREENS 



forms a flat, broad, low top, with branchlets drooping at the 

 ends of the branches. Fortunately, this handsome plant is 

 sold in many American nurseries. Var. glohosa is a low bushy 

 form, well adapted to restricted situations in the garden. 

 Var. atrovirens is dense and compact, forming a low, broad 

 pyramid. It appears to attain a height of twenty feet and 

 perhaps much higher. 



The Carolina hemlock, Tsuga caroliniana, native from the 

 Blue Ridge Mountains to northern Georgia, is very distinct 

 in its character from the common hemlock. It is a smaller- 

 growing tree and has a more compact habit of growth. The 

 foliage is very dark green. The largest specimens at Highland 

 Park are twenty feet tall. Its cones are much larger than 

 those of the common hemlock. In the autumn, when the 

 branches are loaded with the yellowish-brown cones with the 

 scales fully opened, it is an object of singular beauty. It is 

 perfectly hardy, and requires a cool, moist, well-drained soil. 



The Japanese hemlock, Tsuga diversifolia, forms a bushy 

 habit in cultivation, with a number of stems. Wilson says it 

 forms a tree eighty feet tall in Japan. It does not attain any- 

 thing like that height in this country. The conspicuous white 

 lines on the under sides of the leaves contrast very markedly 

 with the dark green on the upper surfaces. 



Siebold hemlock, Tsuga Sieboldii, from Japan, is not as 

 hardy as T. diversifolia. It forms a low bushy tree and does 

 not exceed six feet in height in ten years. It should be planted 

 in a sheltered situation. Wilson says that in Japan, in native 

 conditions, it grows to about the same height as T. diversifolia. 



Douglas fir. 



The so-called Douglas spruce, or red fir of lumbermen, 

 Pseudotsuga taxifolia, is another of the few conifers from the
